Abstract (en)

Heave compensator with adjustable dampening properties comprising a length extension device having an inner space divided by a slide-able piston into a vacuum chamber and a liquid filled chamber, a gas accumulator divided by a slide-able piston into a gas filled chamber and a liquid filled chamber, and eventually a gas tank having an expansion chamber, where the liquid and gas chamber are fluidly connected to each other with valve controlled conduits, and where the device comprises pressure and temperature sensors which register pressure and temperature in the gas- and liquid phases, and where the device further comprises a control unit comprising a signal receiving unit, a writeable computer memory, a data processing unit, and a signal transmitting unit, and where the data processing unit contains computer software which calculates suited amount of gas and gas pressure in the at least one gas accumulator and/or at least one gas tank based on the information of which lifting operation is going to be performed and which thereafter engages activation means such that the suited amount of gas and gas pressure are achieved and maintained during the different phases of the lifting operation.
